Objective: The most commonly used classification system for endometrial hyperplasia is the World Health Organization system which is based on subjective criteria. Another classification system is endometrial intraepithelial neoplasia (EIN) system which uses diagnostic criteria including cytological demarcation, crowded gland architecture,minimum size of 1 mm, and careful exclusion of mimics, and aims to identify a precancer or cancer. The objective of this study was to compare the two classification systems in terms of predicting the presence of a coexistent cancer in surgically treated patients. Methods: Biopsy and hysterectomy specimens of 49 women who were subjected to surgery with a preoperative diagnosis of endometrial hyperplasia (EH) according to the WHO system were re-evaluated retrospectively by using EIN system. Results: Among the 49 patients, 69.4% had complex atypical EH and 75.5% had EIN at biopsy specimens. EIN was detected in 94.1% of complex atypical EH, and 41.7% of non-atypical EH. Nine women (18.4%) had endometrial cancer. Among women with cancer, all had complex atypical EH or EIN. The rate of coexistent endometrial cancer was 26.5% in women with complex atypical EH and 24.3% in women with EIN. Conclusion: Diagnoses of atypical or complex atypical EH and EIN had similar sensitivities and negative predictive values in predicting the coexistent endometrial cancer. Either of these two classification systems may be used safely when an experienced pathologist is available. However, use of the objective EIN system may be preferred whenever possible to prevent diagnostic errors in centers where an experienced pathologist is not available.

Lipoleiomyoma is a very rare tumor which is composed of adipocytes and smooth muscle cells. It is most commonly located in uterine corpus although cervical, ovarian, and retroperitoneal locations were also reported. Lipoleiomyoma located in broad ligament is extremely uncommon and only five cases were reported to date. Here, we report the sixth case of lipoleiomyoma of broad ligament which was diagnosed in a postmenopausal woman who was subjected to exploratory laparotomy with a preoperative diagnosis of a solid adnexal mass suggesting an ovarian malignancy.

Objective: Ovarian granulosa cell tumors are rare malignancies with a relatively favorable prognosis. However, patients still suffer from disease-related mortality. Therefore, the prognostic factors should be clarified. The purpose of this study was to investigate the clinical and pathologic characteristics related with disease recurrence and mortality in adult type ovarian granulosa cell tumors. Methods: Eighty surgically staged patients with granulosa cell ovarian tumor treated at the Hacettepe University Hospital between 1982 and 2006 were retrospectively reviewed. Clinical and pathological characteristics were analyzed. Results: Granulosa cell ovarian tumors accounted for 4.3% of malignant ovarian neoplasms. Mean age was 47.6 years. The most common presenting symptom was abnormal uterine bleeding (53.7%). Endometrial pathology was detected in 51.2% of patients preoperatively. Seventy percent of patients were diagnosed at stage I, and 53.8% of patients received adjuvant treatment. Mean follow-up was 67.5 months. Overall 5-year and 10-year survival was 91% and 86%, respectively. Mean survival was 147.1 months. Recurrence rate was 11.2%. In univariate analysis, advanced stage, advanced age, residual disease after surgery, and need for adjuvant treatment were associated with disease-related mortality and advanced stage disease and absence of initial staging surgery were associated with disease recurrence. However, in multivariate analysis, only initial stage was found to be a significant prognostic factor. Conclusion: Initial stage seems to be the single most important prognostic factor in ovarian granulosa cell tumors. Therefore, a comprehensive staging surgery should be attempted to document the real extent of disease and to estimate the oncologic outcome more accurately.
